Revision 1.6
Features
Advanced Switch Features
IEEE 802.1q VLAN support for up to 16 groups (full-range
of VLAN IDs)
VLAN ID tag/untag options, per port basis
IEEE 802.1p/q tag insertion or removal on a per port basis
(egress)
Programmable rate limiting at the ingress and egress on a
per port basis
Broadcast storm protection with % control (global and per
port basis)
IEEE 802.1d rapid spanning tree protocol support
tail tag mode (1 byte added before FCS) support at port3 to
inform the processor which ingress port receives the
packet and its priority
Bypass feature which Automatically sustains the switch
function between Port1 and Port2 when CPU (Port 3
interface) goes to the sleep mode
Self-address filtering
Individual MAC address for port1 and port2
Support RMII interface and 50 MHz reference clock output
MAC MII interface supports both MAC mode and PHY
mode
IGMP snooping (Ipv4) support for multicast packet Filtering
IPv4/IPv6 QoS support.
MAC filtering function to forward unknown unicast packets
to specified port
Comprehensive Configuration Register Access
Serial management interface (SMI) to all internal
registers
MII management (MIIM) interface to PHY registers
High speed SPI and I2C Interface to all internal registers
I/0 pins strapping and EEPROM to program selective
registers in unmanaged switch mode
Control registers configurable on the fly (port-priority,
802.1p/d/q, AN…)
QoS/CoS Packet Prioritization Support
Per port, 802.1p and DiffServ-based
Re-mapping of 802.1p priority field per port basis Four
priority levels
Proven Integrated 3-Port 10/100 Ethernet Switch
3rd generation switch with three MACs and two
PHYs fully compliant with IEEE 802.3u standard
Non-blocking switch fabric assures fast packet delivery by
utilizing an 1K MAC address lookup table and a store-and-
forward architecture
Full duplex IEEE 802.3x flow control (PAUSE) with force
mode option
Half-duplex back pressure flow control
HP Auto MDI-X for reliable detection of and correction for
straight-through and crossover cables with disable and
enable option
Micrel LinkMD TDR-based cable diagnostics permit
identification of faulty copper cabling on Port 2
Comprehensive LED Indicator support for link, activity,
full/half duplex and 10/100 speed
HBM ESD Rating 3kV
Switch Monitoring Features
Port mirroring/monitoring/sniffing: ingress and/or egress
traffic to any port or MII
MIB counters for fully compliant statistics gathering 34 MIB
counters per port
Loopback modes for remote diagnostic of failure
Low Power Dissipation:
Full-chip hardware power-down (register configuration not
saved)
Full-chip software power-down (register configuration not
saved)
Energy-detect mode support
Dynamic clock tree shutdown feature
Per port based software power-save on PHY (idle link
detection, register configuration preserved)
